Metabolomics of Vitis davidii Foëx. grapes from southern China: Flavonoids and volatiles reveal the flavor profiles of five spine grape varieties

Determining the age of a vineyard is essential for understanding its influence on wine quality and characteristics.

Pinking in white wines occurs unpredictably due to PPO-mediated oxidation of skin-derived flavan-3-ols and hydroxycinnamic acids into quinones that form chromophores [1,2].

Modern viticulture faces a critical paradox. The widespread adoption of clonal selection in the mid-20th century successfully standardized production and reduced viral incidence through sanitization and certification, but unintentionally created a genetically simplified vineyard landscape.

Winegrowing is still characterized by the extensive use of chemical fertilizers and plant protection products, despite strong recommendations to limit these practices. A part of these xenobiotics and metals are then found in grape juice and wine, causing a major health concern, as well as negatively affecting the fermentation process. In recent years, there has been renewed interest in non-Saccharomyces yeasts. These species have a wide phenotypic diversity, which would be exploited to broaden the aromatic palette of wines.

La valanga di fango che si è abbattuta nel Salemitano e nell’Avellinese, provocando decine di vittime, è stata causata in larga misura dalle insufficienti opere idrauliche e dalla manca­ta manutenzione di antiquati canali idrici.
